Add a variant of gdk_drag_begin that takes the start position
in addition to the device. All backend implementation have been
updated to accept (and ignore) the new arguments.
Subsequent commits will make use of the data in some backends.
In commit 2c61316677 we avoided emitting
the style-changed signal if no CSS property changed.
Unfortunately, this also caused CSS styles to not be updated when
animations started if those animations did not change any CSS value
immediately. In those cases the animation would just never start.
The obvious example was the spinner.
Catch the case where a CSS style did not change and don't emit the
style-changed signal in that case.
This saves not only the emission of the signal, but also doesn't cause
invalidation in child nodes, which would previously get a PARENT_STYLE
Instead of having old and new style, now have a GtkCssStyleChange opaque
object that will compute the changes you are interested in for you.
This simplifies change signal handlers quite a bit and avoids lots of
repeated computation in every signal handler.
We were only storing the dialog size on unmap, but resetting to the
stored default value more often, e.g. on focus-out. This was causing
the dialog to 'jump back' to its remembered size after the user
manually resized it, leading to frustration and bug reports.
Instead, save the dialog size on every ::size-allocate of the toplevel.
To avoid needlessly spamming dconf, only write the new value if it
changed.
In Wayland, the hotspot of a DND icon is set using the buffer offset in
wl_buffer.attach. To implement this, add a private API to cause the
next wl_surface.attach to offset the new buffer with a given offset.
Setting a DND icon hotspot sets this offset while also queuing a redraw
of the window to trigger the wl_surface.attach.

...in the process simplified the touch-selection styling, check
and radios not fixed there since I'm going to add proper osd assets
for those (istead of forcing the dark variant assets there as before).
The name gtk_text_*_begins_* was used only for begins_tag(). All other
similar functions use "starts": starts_line(), starts_word(), etc.
So for consistency, add gtk_text_iter_starts_tag() and deprecate
gtk_text_iter_begins_tag().
Also change (allow-none) to (nullable), to use the new annotation.
